SpaceTV-1
SpaceTV-1 is a 4K ultra-high-definition external camera system designed specifically for continuous Earth observation and live streaming. It is mounted outside the ISS on the Bartolomeo platform — not behind a window — and operates 24/7 when communications allow. It orbits Earth every ~90 minutes at ~7.7 km/s.

Cameras
Nadir Camera
Pointed straight down toward Earth, best for observing land, coastlines, cities, weather systems, and night-time activity.
Docking Camera
Oriented along the ISS structure, showing whatever spacecraft is docked to the forward docking port of the ISS. We get to see spacecraft docking and undocking if those events happen during orbital daytime.
Horizon Camera
Angled toward Earth's limb, ideal for sweeping views over the oceans, large cloud systems, and the curvature of the planet.
